In a medical report released early this morning, INDYCAR disclosed that Hawksworth suffered a myocardial contusion in the wreck. After being evaluated by INDYCAR medical director Dr. Michael Olinger at Pocono, the British driver was transported to Lehigh Valley Health Network in Allentown, Pennsylvania, where he was kept overnight for observation.

Hawksworth, who drives the No. 98 Integrity Energee Drink Honda for Bryan Herta Autosport, was not cleared to race today and will be re-evaluated by INDYCAR’s medical team before being allowed to compete in next weekend’s Iowa Corn Indy 300 at Iowa Speedway.

Late this morning, Curt Cavin of the Indianapolis Star reported that the tub and gearbox of Hawksworth’s car broke in the crash, and that Hawksworth himself was still in the hospital:

Update on @BHA: Tub and gearbox broke in crash. It was fixable, but Steve Newey said not fair to rush a driver out there. #IndyCar

In his wreck, Hawksworth had the back end of his car come around on him in Turn 1 before he impacted the wall flush on the left side.

The British driver was checked, cleared and released from the infield care center after the crash, and IndyCar Radio reported at the time that he had only banged his knee inside the cockpit.

In an interview with IndyCar Radio, Hawksworth said he was confident that he’d be able to take part in qualifying later on Saturday if BHA repaired the car in time. But neither he or the No. 98 returned to the track for the rest of the day.

Unfortunate but I applaud the team’s caution. There aren’t many spare drivers out there with open wheel experience at Pocono and this isn’t the kind of track where someone can just get up to speed in the race itself.
